Application filed July 25, 1914. `Serial No. 853,238.

To all whom t may concern.'

Be it known that I, STEPHAN A. BLAnK, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in KeylessLocks, of which the following is a speciication. i

This invention relates to improvements in locks, and particularly tothat type known as permutation, in which no key is used.

The objects of the invention are, to provide a lock in which theengaging elements can be inserted and secured irrespective of theposition of the mechanical elements of the lock body. Second, to providea lock particularly adapted for traveling cases, valises, satchels andthe like, which it is desired to secure in a closed position. againstinadvertent or unauthorizedopening.' Third, to provide a lock of theclass described, comprised of essentially simple elements, readilyoperated and which Yailcord unusual convenience and security. T-hese andother allied objects are obtained by the novel constructionandcombination lof parts, hereinafter described and shown in theaccompanying drawings, in which:

Figure 1 is a plan view of theY lock. Fig. 2 is a front elevation of thesame, showing the hasp plate in engagement. Fig. 3 is a bottom plan viewof the lock, the parts beinn' shown in position for unlocking. Fig.

is a sectional view taken on line 1 4 of- Fig. 3. Fig. 5 is aperspective view of the bolt or hasp engaging element, and, Fig. 6 is anenlarged sectional view taken on line (5 5 of Fig. 4. I

The invention is comprised of asuitable casing 10 which may be formedfrom a single sheet of material and provided with ears or extensions 12'for convenience in securing the lock in position upon the article towhich it is applied.

Upon the hinged member of the article is attached a hasp plate 15provided with projecting hooks 16 adapted to enter openings 11 formed inthe adjacent side of the lock casing andthere become engaged with thesliding bolt 18 normally pressed toward one end by reason of the spring19. This bolt 18 has an end member 20 formed integrally with it at aright angle, the eX- treme end of which acts as a guide within thecasing l0 to maintain the bolt in proper position. The other end of thebolt 18 is provided with an arm 21 for a similar purpose and also alcentral upstanding and 'outwardly turned projection 22 against whichone end `of the spring abuts, the other end being held againstl the endwall of the casing.

The plate 23 is slidably contained adja-` cent to the bolt 18 and has atone end a vertical wall 211 against which the bolt member 20 normallyabuts. This plate is provided with elongated openings 25 and 2G neareach end into which extend projections 27 and 28 respectively. tralraised lug 29 doubling the thickness of the plate, and having at one enda projection 29', corresponding with the projection 28 on the plateimmediately below; secured in the plate and lug is the stem 30 of thecenter knob 30 which is adapted to move longitudinally in a groove 31formed in the top of the casing l0. At each side of this center knob areother knobs 32 and 33, similar in appearance, which are provided withdialsv31l. and 35 on which are numerals and other characters signifyingthe position of the disk tumblers 36 and 37 rigidly attached to thestems of these knobs immediately beneath the casing shell and inregister with the mentioned openings 25 and 26 inthe slidable plate 23.In both of these tumblers .are notches 36" and 37 suited to receive theprojections 27 and 28. Also upon one or both of these knobs is a freelyrotatable disk tumbler l0 similar in character to those previouslydescribed but capa-ble of turning upon the stem. `At one side of each ofthese upper tumblers is inserted a pin 11 adapted to -make contact witha carrier l2 rigidly secured to the eXtreme inner end of the knob stemand arranged to transmit motion through contact with the pin to theoutermost tumblerslO which is arranged to be in the same horizontal.plane as the lug 29. These tumblers 4l() are made with indentations 410coincident with the characters upon the index or dial connected with theAlso on this plate is a cen-r knobs and adapted to receive pressure frombe secured between it and the article to' which the lock is applied.

In operation, the parts being properly assembled and attached to thearticle to be locked, itwill be noticed that the hooks 16 on the haspplate 15 may be entered through the openings 11 in the Jfront wall ofthe lock casing, the result being to force the bolt 18 to move withinthe casing compressing the spring 19 sufficiently to allow this A onlytoturn the vdial index until a pre-arranged character is in properrelation rto some marl; on the outer casing; butv when a plurality oftumblers are used, the loose tumblers are brought into position by thecarrier 4t2 and pin 11 and held by reason ot' the spring tension onthem, thus reversing the direction of rotation until the rigid tumblersare broughtinto a corresponding position which can be ascertained by theindex figures on the dial secured to the knob.

While the lforegoing describes and indivrca tes the application of thelock, it is not desired to be constrained to the exact constructionshown, as obviously both sets of tumblers may bemade in either of thestyles shown, o-r both may be alike as preferred, and that there areother modifications which can be made without departing from Vthe scopeof the claims hereby appended.

' Having thusv described my invention, what I claim as new and desire tosecure by Letters Patent, is z 1. In a device of the class described,the combination with a casing, a spring actuated bolt and a slidingplate combined therewith, said plate having elongated apertures, of aknob operative with said plate, tumblers in the mentioned apertures,knobs upon which said tumblers are iixed, a loose tumbler mounted on oneof said knobs beyond said fixed tumbler-s and means ior rotating saidloose tumbler independently.

2. In a device of the class described, the combination with a casing, asliding plate,

ra bolt having two engaging points operable 3. In a device 01: the classdescribed, the

combination with narrow elongated casing, a plate slidably mountedtherewithin, said plate having elongated openings, projections integralwith said plate extending into the mentioned openings, tumblersrotatably disposed in a straight line uniformly spaced andy slotted toreceive said projections, means for operating said tumblers, a boltoperable by said plate, said bolt being also independently movable andmaintained normally in a locking position, and means intermediate ofsaid tumbler operating means for actuating said bolt.

,4. In a, device ot' the class described, the combination with a casingand a hasp plate having members adapted to enter within the casing, of abolt engageable with said mem- Y bers, a plate slidable in said casinghaving a part i'or disengaging said bolt from said members, a raised lugon said plate, tum blers engaging with said plate, a loose tum* blerengaging with the raised lug on said plate, means ior operating all ot'said tumlblers independently and means for actuating said plate.

In testimony whereof I have signed my name to this specification in thepresence oi two subscribing witnesses.
